.To all whom t may concern: v

lEle it .known that I, EDWARD Haar, a Citi- -zen of the United States,residing at Easton, inthe county oit Nortliai'npton and State of Peursy'lvi nia, have invented certain new 'and Jeful lmprovements inChemical Apolf which the following is a` full, 'l exact description.invention relates to chemical appaweighing, absorbing, washing, or wisetreating gases by passing the rough and in intimate Contact with aliquid or solid, and `its chief object is to provide an improvedapparatus for the purpose, of sim-ple character, which can y, be-readily manipulated and can be easily eleaned and charged. To this' andother ends the ention consists in the novel leafter described.- .rredform the invention oomie,'preferably of glass, having la wide ino, i tovpermit easy introduction of large solids, .as for example large glassbeads or balls such as are used for the pnrpose-ef carrying a ilm ofreagent, say sul- 'urie s0 as to expose a large area to the current ofgas, or for the purpose of breaking up the current into tortuousstreams. The gas is introduced through a tube mniiected to theloweiportion of the bottle, ar passes out through a tube connected wi"the upper portion, preferably the neelf. The two tubes are connected to-v the saine valve cock, so that both the inlet and the o tiet areclosed simultaneously and opened simultaneously.

' @The embodiment thus briefly outlined is illustrated in thevaccompanying drawings, in which the ligure shows the apparatus in ilvertical section. I Tlieve. bottle is designated A, and is provideswith a neck B, preferably wide,

. so as to filling with solid bodies or' rather large size when desired.The outlet tube C e t from the neck of the bottle, .and the hollowstopper D has a lateral aperture whieh b y a slight turn er the stoppermay carried out of orinto register with the orifice oli the outlet tube.The inlet tube opens into-the' lower par*U of the bottle. and both tubesentend inte con I, nection wi a valve or cock havinga plug G. The i. teris `integral withl the 'tube H and has angular passage l extending S5from the endet tube H into positionfor registry wit".

the tube F; and the tapered.

shell J, in which the plug Gr turns, is ntegral with tube l. rlllie plugG also has an angular passage L extending from the tube K to a' pointwhere 'it will register with tube C when passage l is in registrv withtube F. The te be treated is de ivered to the tube H by inea-ns ofrubber tubing slipped over the end of the tube,'and the residuum, ifany, is carried away by like tubing fitted on the end of tube K. l

It will be observed that a turn of the plug G closes or opens both theinlet tube F and the outlet tube C.' Preferably the passages l and L,are ot such size that not more than a quarter turn of the Cock issuiiicient to open or close the tubes. A slight turn (say a quarter) ofthe stopper D closes the outlet tube only, as may be desirable when apres sure is to be produced in the bottle.

The apparatus illustrated is designed particularly for absorbing carbondioxid or other acid gas and determining its amount, but of course canbe used lor other purposes as well, as for example for washing. ln theformer case the bottle is charged with suitable absorbent, and isweighed with its contents. rl`he gas .is then passed through, and thebottle and contents weighed again. The increase in weight then gives theamount of gas absorbed.

- The valve plug Gr being removable as readily as the stopper D, theapparatus is easily cleaned and rinsed.

lt is to be understood that the invention is not limited to theapparatus herein specifically illustrated but can be embodied in otherforms without departure from its spirit as delincd by the followingclaims.

l claim:

l. An apparatus for gas-absorption and other purposes, comprising avessel having a removable closure, gas inlet and outlet tubes connectedto the lower and upper portions ot' the vessel respectively, and aAsingle valve connected to both tubes independently of the closure, tocontrol both tubes simultaneously.

2. An apparatus for gasabsorption and lll) ter with .said outletI tubebyrotating the A closure, a gas inlet tube eonneeted with the 'lowerportion of the vessel, and means for delivering gas to theinlet tube andcarrying gas away from the outlet tube, said nieans including a singlevalve controlling both tubes. l

An apparatus for gas-absorption and omer purposes, comprising a vesselhaving a neck B at its top, a gas outlet tube C leading laterally fromthe neck, a rotatable elosure D seated in the neck aiul'liaving anoutletl aperture E adapted to be carried into and out of registry withsaid outlet tube by rotating the closure, a gas inlet tube F eonneetedto the lower portion of the vessel, a Valve shell J connected to the gasinlet and 'outlet tubes and having an axial diseliai tube K, and aValve-plug G rotatable in l shell and having a gas-delivery tube ll aprovided with a passage ll leatfling :fr the Said deliveryv tube intoposition 'for istry with the said inlet tube and a L extending from aposition for regi with the said outlet itube into registry w the saiddischarge tube, wherein,v rotation the plug controls both the inlet undthe outlet tube simultaneously.
